KCET 2017: If A is a square matrix of order 3 × 3, then |KA| is equal to (A) K|A| (B) K2|A| (C) K3|A| (D) 3K|A|. In 1933, Raymond Paley discovered the Paley construction, which produces a Hadamard matrix of order q + 1 when q is any prime power that is congruent to 3 modulo 4 and that produces a Hadamard matrix of order 2(q + 1) when q is a prime power that is congruent to 1 modulo 4. A zero matrix or a null matrix is a matrix that has all its elements zero. Hence rank of matrix A = 3. The process by which the rank of a matrix is determined can be illustrated by the following example.
